Each SmallGarden 2 comes equipped with a water port on the reservoir lid. The goal of this is so users can add water to the reservoir with out disturbing any of the plants. To add water, just pour into the port labeled below.
When adding water, your SmallGarden will let you know how full the reservoir is by flashing the notification LED following colors:
Red - reservoir is 25% full
Orange - reservoir is 50% full
Yellow - reservoir is 75% full
Green - reservoir is 100% full
